Create a heap allocated clone of the object this method is called for.

The caller is responsible for deallocating the clone when he is done with it.

Returns

A heap allocated copy of the object this method is called for.

Implements zipios::FileEntry.

Reimplemented in zipios::ZipCDirEntry.

getComment()

string zipios::ZipLocalEntry::getComment ( ) const

virtual

Returns the comment of the entry, if it has one.

Otherwise it returns an empty string.

Returns

the comment associated with the entry, if there is one.

Implements zipios::FileEntry.

Reimplemented in zipios::ZipCDirEntry.

getCompressedSize()

uint32 zipios::ZipLocalEntry::getCompressedSize ( ) const

virtual

Returns the compressed size of the entry.

If the entry is not stored in a compressed format, the uncompressed size is returned.

Returns

the compressed size of the entry. If the entry is stored without compression the uncompressed size is returned.

Implements zipios::FileEntry.

References compress_size.

getCrc()

uint32 zipios::ZipLocalEntry::getCrc ( ) const

virtual

Returns the Crc for the entry, if it has one.

FIXME: what is returned if it doesn't have one?

Returns

the Crc for the entry, if it has one.

Implements zipios::FileEntry.

getExtra()

vector< unsigned char > zipios::ZipLocalEntry::getExtra ( ) const

virtual

Returns a vector of bytes of extra data that may be stored with the entry.

Returns

A vector< unsigned char > of extra bytes that may potentially be associated with an entry.

Implements zipios::FileEntry.

References extra_field.

getFileName()

string zipios::ZipLocalEntry::getFileName ( ) const

virtual

Returns the filename of the entry.

Returns

Returns the filename of the entry.

Implements zipios::FileEntry.

getMethod()

StorageMethod zipios::ZipLocalEntry::getMethod ( ) const

virtual

Returns the method used to store the entry in the FileCollection.

Returns

the storage method used to store the entry in the collection.

getName()

string zipios::ZipLocalEntry::getName ( ) const

virtual

Returns the full filename of the entry, including a path if the entry is stored in a subfolder.
